IPC: G01L9/08
Filed: 1979-02-20
Abstract: 1. Method for the manufacture of a piezoelectric transducer element, particularly for incorporation in pressure, force or acceleration detectors, consisting of a securing part and at least one annular shear element of piezoelectric material with an open longitudinal slot shrunk-fitted on to the securing part by means of an outer surrounding shrink-ring, characterized in that the annular shear element is first assembled on the securing part by means of a likewise slotted setting-up ring encircling the shear element and is than firmly shrunk on to the securing part in known manner by the cooling of the heated shrink-ring positioned externally around the setting-up ring, whereby the setting-up ring prevents overheating of the annular shear element during the shrinking process.

Abstract: A video consisting of data organized in the form of a plurality of images is transmitted in a communication network. The method comprises a step of coding images with motion compensation, which consists in compressing the images of the video and in creating dependencies between compressed images, a step of scheduling the transmission of packets representing the compressed images, which consists in sending the compressed images over the network in a selected order, and a step of controlling the rate of the video. At least one of reconsidering the selected order of sending already compressed but not yet transmitted images and deleting at least one compressed image is performed at the time of coding a new image. Furthermore, the dependencies between the new image to be compressed and the compressed images are selected by taking into account the reconsidered sending order at the time of coding the new image.
